Class type

IPv4 frame of a packet.

type tp =
  1. | Tcp of Tcp.t
  2. | Udp of Udp.t
  3. | Icmp of Icmp.t
  4. | Igmp of Igmp.t
  5. | Unparsable of nwProto * Cstruct.t

The type tp represents packets at the transport protocol level, which are encapsulated within the IPv4 payload. At present, we only support TCP, UDP, ICMP and IGMP explicitly; otherwise, the raw bytes and IPv4 protocol number are provided.

val sexp_of_tp : tp -> Ppx_sexp_conv_lib.Sexp.t
val tp_of_sexp : Ppx_sexp_conv_lib.Sexp.t -> tp

  6. chksum : int16;
